Description

The invention is intended for use in heat exchange devices and can be used in mechanical engineering and construction for space heating. The well-known "HEAT EXCHANGER ON HEAT PIPES", RU, Patent No. 2310804, C1, IPC F28D 15/02 (2006. 01). Application: 2006116958/06, 05.17.2006.

The heat exchanger is made of one or several modules of the same type, it contains a housing with a bundle of heat pipes located horizontally in rows arranged inside. Pipes are installed in each row with gaps forming slotted channels and perpendicular to the direction of the heat-exchanging media. The evaporation sections of the heat pipes are located inside the housing with the formation of a common evaporation zone. Condensation sections of pipes are outside the housing. Heat pipes of the common evaporation zone are arranged mutually perpendicular, alternating rows and are fixed in the corresponding adjacent walls of the housing. The module is additionally equipped with a mirror-mounted, similar housing with identical placement and fixing of heat pipe bundles and a common evaporation zone in it. Each row of heat pipes of the additional housing is located between the corresponding series of heat pipes of the main body with the formation of common condensation zones located in the common module housing. The common evaporation zones and the general condensation zones of the module are located in mutually perpendicular planes, along the diagonals of the general module housing with the formation of respectively separate channels for the passage of each of the heat-exchanging media.

The disadvantages are the complexity of the design, the high energy consumption for heating the structure itself and, in case of depressurization, the inability of the normal functioning of all heat pipes

The well-known "HEAT PIPE", SU, Patent No. 1140528, A1, IPC ⁷ F28D 15/02. Application: 3578248/06, 04/12/1983.

A heat pipe with evaporation, transport and condensation zones, comprising a housing made cylindrical in the transport zone, and spherical in the evaporation and condensation zones, and an insert coaxially installed in the housing, forming steam and condensate pipelines and having a cylindrical shape in the transport zone, characterized in that that, in order to intensify heat transfer, the housing in the evaporation zone is made circular and equipped in this zone and the condensation zone with deflectors in the form of spheres connected to the insert and arranged coaxially spherical parts of the body (Prototype).

The disadvantages are the complexity of the design and the presence on the pipe surface of additional deflectors.

1. A pipe-in-pipe type heat exchanger comprising inner and outer cylindrical shells installed coaxially with an annular gap and forming a cavity for the working fluid, inlet and outlet manifolds with nozzles, characterized in that additional shells forming cavities are installed in the cavity of the heat exchanger.

2. The heat exchanger according to claim 1, characterized in that the additional cavity is connected to the cavity for the working fluid of the heat exchanger.

3. The heat exchanger according to claims 1 and 2, characterized in that the additional shells are mounted on pylons in which channels for supplying and discharging the working fluid are made.

4. The heat exchanger according to claims 1 to 3, characterized in that the holes connecting the cavities are made in the wall of the additional shell.

The disadvantage is the large amount of energy for the operation of the device, the complexity of the design.

The aim of the invention is the creation of convenient for installation, cheap, simple design of the heat exchanger.

The technical result (technical solution) is achieved by the fact that the evaporation zone of the working fluid is in the pipe, which is plugged on one side in the lower part of the pipe, and the whole pipe is in the coolant, and the condensation zone is at least between two profiled metal sheets, and the connection is in cross section sheets can look like an ellipse with two sheets, like a triangle with three sheets, like a parallelogram with four sheets, like a star with 10 or more sheets, and the condensation zone is located above the evaporation zone. This gives the necessary advantage over the prototype.

Statics.

Figure 1 shows the "Heating radiator from the heat pipe" (1), made so that the evaporation zone (2) of the working fluid (3) is in the pipe (4), muffled on one side in the lower part of the pipe (5), and the whole the pipe (4) is in the coolant (not shown in the drawing), and the condensation zone (6) is at least between two profiled metal sheets (7), and in the section the connection of the sheets (7) may look like an ellipse (8) with two sheets (Figure 2), like a triangle (9) with three sheets (Figure 3), like a parallelogram (10) with four sheets (Figure 4), like a star (11) with 10 or more sheets (Figure 5), and the condensation zone (6) is located above the evaporation zone (2).

Work.

The coolant flows through the pipes to the pipe (4). The evaporation of the working fluid (3). The vapor of the working fluid (3) condenses on the inner walls of the profiled sheets. In this case, the same amount of energy is released as for evaporation. The shape in the section of the connection of the sheets (7) is determined by the required heat transfer area from the radiator (1), because thermal conductivity of the heat pipe (12) is a thousand times greater than any metal. The heat pipe (12) is capable of transmitting a huge amount of heat, and only the ability to take this heat from the heat pipe (12) in the condensation zone limits its characteristics. For this, a different section of the sheets (7) is made for the most optimal condensation area of the working fluid (3).

Technical and economic characteristics are significantly higher than the prototype, because the number of parts is reduced and production is simplified.
